Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of soft debris removal equipment, and particularly relates to a sieve-type soft debris removal device. Background Technique
[0002] When coal is transported to the coal storage yard, there is often a problem that the debris removal machine cannot handle large coal blocks because a coal crusher is not installed on the conveying section, resulting in a large amount of soft debris in the coal yard and the roller screen.
[0003] Currently, the existing debris removal machine is a rotary hook-type debris removal machine. Since it requires crushing by a coarse crusher to crush coal blocks into small pieces for debris removal, it causes problems such as difficult maintenance and increased energy consumption. Therefore, there is an urgent need for a soft debris removal device that can effectively separate large coal blocks and soft debris for treatment without changing the original equipment. Content of the Utility Model
[0004] The purpose of the utility model is to provide a sieve-type soft debris removal device to solve the problems of difficult maintenance and increased energy consumption caused by the existing rotary hook-type debris removal machine in the background technique, which requires crushing by a coarse crusher to crush coal blocks into small pieces for debris removal.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A sieve-type soft debris removal device includes: a coal dropping cylinder. One side of the coal dropping cylinder is provided with a conveyor belt for conveying coal from the conveyor belt into the coal dropping cylinder. Inside the coal dropping cylinder and in the direction of coal falling, a coarse sieve plate is arranged for preliminarily screening the coal conveyed by the conveyor belt. A fixed shaft is arranged below the coarse sieve plate on the inner side of the coal dropping cylinder opposite to the conveyor belt. The fixed shaft is axially provided with a number of first arc-shaped rods at intervals to form a fine sieve plate. A rotating shaft is rotatably arranged inside the fixed shaft. The rotating shaft is axially provided with a number of second arc-shaped rods at intervals to form a debris turning plate. The second arc-shaped rods pass through the arc-shaped cutouts adjacent to the first arc-shaped rods for the debris turning plate to rotate within the arc range of the arc-shaped cutouts. One end of the rotating shaft extends outside the fixed shaft, and the extension is connected to a driving device for driving the rotating shaft to rotate. A debris collection bin is arranged on the other side of the coal dropping cylinder. Coal enters the coal dropping cylinder through the conveyor belt. After preliminary screening by the coarse sieve plate, it falls onto the fine sieve plate. After the fine sieve plate hooks the debris, the rotating shaft drives the debris turning plate to rotate counterclockwise through the driving of the driving device, and the debris enters the debris collection bin.
[0007] Furthermore, it further includes: a floor slab. The floor slab is provided with holes for installing the coal dropping cylinder.
[0008] Furthermore, the debris collection bin is placed on the surface of the floor slab.
[0009] Further, a sundry cart is arranged at the bottom of the sundry collection bin for transporting the collected sundries.
[0010] Further, a funnel curtain is arranged between the sundry collection bin and the sundry cart.
[0011] Further, the arc length of the arc-shaped incision is less than the circumference of the fixed shaft.
[0012] Further, the driving device is a motor driving device or an electric push rod.
[0013] Further, the width of the coarse sieve plate is 100 mm, the thickness is 20 mm, and the surface of the coarse sieve plate forms an angle of 45° with the vertical direction of the coal dropping cylinder.
[0014] Further, the width of the fine sieve plate is 50 mm and the thickness is 20 mm.
[0015] Further, sawteeth are arranged on the upper surfaces of the fine sieve plate and the sundry turning plate.
[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] The present utility model is improved on the basis of the combination of the original coal dropping cylinder and the conveyor belt. By arranging a coarse sieve plate on the inner side of the coal dropping cylinder and in the direction of coal falling, and at the same time arranging a fixed shaft on the inner side and at the lower left part of the coarse sieve plate, a first arc-shaped rod is arranged along the axial direction on the side of the fixed shaft to form a fine sieve plate, a rotating shaft is rotatably arranged inside the fixed shaft, and a second arc-shaped rod is arranged along the axial direction on the rotating shaft to form a sundry turning plate. The second arc-shaped rod passes through the arc-shaped incision adjacent to the first arc-shaped rod, and one end of the rotating shaft extends outwards to connect with the driving device. Finally, a sundry collection bin is arranged on the left side of the coal dropping cylinder. In this way, when the coal falls into the coal dropping cylinder and is successively screened by the coarse sieve plate and the fine sieve plate, the fine sieve plate hooks the sundries. Finally, driven by the driving device, the sundry turning plate rotates counterclockwise, and the sundries enter the sundry collection bin. By repeating this process, the purpose of removing the sundries on the surface of the coal is achieved, and the problems of difficult maintenance and increased energy consumption caused by the existing rotary hook type sundry remover, which requires crushing by a coarse crusher to crush the coal blocks into small pieces for sundry removal, are solved.
